Answer:

Simplifying

8x + -3 = 5(2x + 1)

Reorder the terms:

-3 + 8x = 5(2x + 1)

Reorder the terms:

-3 + 8x = 5(1 + 2x)

-3 + 8x = (1 * 5 + 2x * 5)

-3 + 8x = (5 + 10x)

Solving

-3 + 8x = 5 + 10x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10x' to each side of the equation.

-3 + 8x + -10x = 5 + 10x + -10x

Combine like terms: 8x + -10x = -2x

-3 + -2x = 5 + 10x + -10x

Combine like terms: 10x + -10x = 0

-3 + -2x = 5 + 0

-3 + -2x = 5

Add '3' to each side of the equation.

-3 + 3 + -2x = 5 + 3

Combine like terms: -3 + 3 = 0

0 + -2x = 5 + 3

-2x = 5 + 3

Combine like terms: 5 + 3 = 8

-2x = 8

Divide each side by '-2'.

x = -4

Simplifying

x = -4
